It is a Frommer Model 1937, produced by the Frommer factory in Hungary in 1941 for Germany. A 50,000 piece contract was issued in 1941 for a 7.65mm (.32 ACP) version of the Frommer Model 1937 9mm Short (.380). Most of these contract guns were sent to the Luftwaffe, and the contract was eventually extended through 1944 with some 85.000 produced.
